COMBINED TYPE-WRITING- AND COMPUTING MACHINE.

pecially adapted to enable machines to be.

quickly altered to do writing which may require computation in several columns, and in which the position of said coiumns may vary from time to time with the particular style of work-sheetv which is being written on. Such sheets are used in railroad offices.

The typewriting machine, as usual, comprises a letter-spacing traveling carriage tocontrol the relation of the types to the worksheet. The computing mechanism comprises a master 'wheel or denominational selector, which is arranged to successively engage a gang of wheels, which form a totalizer, in such a manner that the totalizer moves relatively to the master wheel with a step-bystep movement corresponding to the movement of the typewriter carriage. Thus the computing mechanism comprises one fixed and one traveling element. The extent of movement of the traveling element may be considerably less than that of the typewriter carriage, and the. number of com uting wheels is correspondingly considerab y less than the number of letter-spaces in the travelof thetypewriter carriage.

One purpose of the present invention is to enable columns of numerals at separated points in the travel of the typewriter carriage to be computed successively on adjacent groups of computing wheels, without having to have a largenumber of unused computing wheelsbetween the various col umns of numbers; For this purpose, the totalizer may be composed of a series of computing wheels and carry-over devices, which taken together may form a continuous train, and columns of figures may be computed in said train beginning at any selected computing wheels. To enable this to be done, a connection may be established between the traveling element of the computing mechanism and the typewriter carriag'e,.so as to be at times eifective' and at times ineffective; with. a result that some times the traveling Specification of Letters Patent.

element of the computing mechanism moves I ranged to be intercepted by a tabulating stop or other tappet on the carriage of the typewriter. Until this hook is engaged by the stop of the tabulating mechanism, the typewriter carriage may travel alone, but when said stop catches said hook, the typewriter carriage and the traveling element of the computing mechanism may be arranged to travel together until a disconnector moves the hook positively out of engagement with said stop. There may be a series of stops similar to the one above described so arranged that each one successively will engage said hook, and be released therefrom. From this, it will follow that when the hook has'been engaged by one stop and released therefrom, the travelin element of the computing mechanism wil remain at rest until said hook is engaged by a second stop.' In this way matter may be written on the worksheet after the first computation is effected, and before the second one is begun, without in any way moving the traveling element of -the computing mechanism, or to put it in other words, matter may be written overany desired number of letter spaces on a worksheet, while the traveling element of the comput-ingmechanism is no way affecting the relation of the master wheel to the computing wheels.

In the form of the invention: herein illustrated, it will be seen that the ordinary tabulator stops are employed which are settable manuall at will along a rack bar, while a series 0 disconnectors may be permanently set at what is thepreferred width for a column of figures in the totalizer. If a column of figures of extraordinary width is to be computed, one or more of the intermediate disconnectors may be set at inefiective position and the tabulating sto; 5; may, if desired, be shifted to corre ond therewith.

Referring more particularly to the separate parts of 'thisinvention as embodied in the form" shown in the drawings, and as taken in connection with" an V Underwood typewriting machine, 1 indicates the key lever which operatesthrough a sub lever 2 a type bar 3, so that the latter will strike rearwardly against the front side of a platen 4 mountedon a carriage 5. The carriage 5 is mounted to move in the usual manner on tracks 6 and 7, and is driven by a spring drum 8. The carriage 5 is provided with a rack 9 mounted on pivoted arms 10, so as to be capable of moving into and out of engagement with a pinion 11 connected to an escapement wheel 12, the dogs which permit the movement of the latter at each stroke of a character key being omitted. I

For the purpose of spacing the carriage for tabulating to difierent major columns or zones and digit columns in such zones, there are provided tabulating keys 13, the rear ends of which raise stop bars or plungers 14, provided at their upper ends with stopengaging portions 15, which are adapted to be projected into the path of stops 16 by the movement of the tabulating keys 13. The stops 16 are shown to be bifurcated, so as to engage in slots 17 and 18 provided on the upper and lower surfaces of a bar or rack 19 carried by the carriage 5.

The bars 14 are each provided with a pro jection114 which engages a universal bar 214 on a lever 314 connected by a link 414 to a lever 514 carrying a roller 614 adapted to engage under the rack 9, to lift the same from engagement with the pinion 11 at the operation of any of the tabulating .keys 13.

The computing mechanism is of a type such as that described in the application of \Vright and Degencr No. 543.603, tiled February 12, 1910, in which a master-wheel shaft 20 is rotated automatically at each depression of a numeral key a predetermined amount corresponding to the value of the particular numeral key. The rotation of the shaft 20 is transmitted in this case to a master wheel 21, .which is shown as being mounted on an arbor 22 slidably splined on the shaft 20.' the latter being shown as squared for this purpose. The master wheel 21, which is mounted on the arbor 22, is provided with teeth 23 which project between teeth 24, forming internal gears on disks 25; the latter are also provided with external teeth 26 which mesh with gears 27 pro- 28. Any suitable carry-over mechanism may connect each computing wheel with the one above, so that said one above is turned one unit when the lower one turns to read .ze-ro. With this carry-over mechanism the wheelsin the totalizer form a continuous train. The arbor 22 is mounted to slide back and forth on theshaft 20, so that the master wheel 21 will engage successively with the juxtaposed disks 25, whereby the rotation ofthe shaft 20 will be transmitted successively to the several disks, and thus to the several computing wheels.

In order to permit this movement, the arbor 22 is in the form of a sleeve mounted on the shaft 20, so that it is capable of sliding back and forth in and out of the series of disks 25. To obtainthe movement of the arbor, it is provided with an arm 30 which 110 vided with computing or-numeral wheels slides on rods 29 and is connected with a rack 31 engaging a gear 32 mounted on a shaft 33. The shaft 33 extends to the rear of the machine, where it is provided with another gear 34 meshing with a gear 35, which latter engages with a rack bar 36 slidingly mounted in a channel guide 38 and further mounted by means of channel rollers 39 and 49.

The bar 36 haiipivotally mounted thereon a catch or hook 41 which is adapted to engage any of the stops 16, or other stops, for the purpose of operatively connecting the rack bar 36 to the carriage 5. This mechanism just described may be termed the connector of connecting mechanism between the carriage and the movable elements of the computing mechanism, which in this instance consists of the arbor and master wheel.

' In this instance, the catch 41 is shown as being provided with a tooth 42 which is spaced apart from a projection 43 by a slot.

44 (Fig. 13), so as toform anotch into which any one of the stops 16 can fit, so as to positively connect the catch to the carriage. The catch is normally held in its uppermost or active position by a spring 45 which engages at one end in a cavity 46 (Fig. 13), provided in the bar 36, and at the other end with a pin 47 provided on the catch 41. a

For the purpose of disconnecting the traveling element of the computing mechanism from the operative connection with the carriage at predetermined intervals in the movement of the carriage, there are provided a plurality of disconnectors 48 which are adapted to force the catch 41 from engagementwith the particular stop 16 with which itjhappens to be connected. While this operation might be accomplished by the direct engagement of the disconnectors 48 with the catch 41, for the purpose of obtaining a quick movement, it is desirable to interpose a tripper 49, which is shown as pivotally mounted on the bar 36 adjacent the 'catch41 and is provided Withan arm 50' which projects over a finger 51 on the catch 41. When the tripper 49 reaches the disconnector '48, another arm 52 on the tripper 49 forminga bell crank lever, comprising a notch 53 is engaged by a toe 54 on a trip 55 ofeach of the disconnectors 48, thereby being swung, so that the arm 50 depresses the catch 41 and frees it from the stop 16. The trip 55 is shown in the form of a lever pivoted intermediate its ends, and provided at the end opposite to that at which the toe 54 is located with a roller 56, whereby each of the stops 16 may disengage the toe 54 from the tripper 49, after the trip 55 has accomplished its" purpose of disconnecting the catch 41 from the same stop. This action is shown clearly in Fig. 10, where the stop 16 is shown to have depressed one end of the trip 55, raising the toe end from engagement with the tripper 49. A spring 57 is provided for each trip, which springs normally hold 1 the trips 55 in such a position that the toes 54 thereon will be ready to engage the tripper 49. A spring 58 is also provided, which holds the tripper 49 in engagement with the finger 51 of the catch 41. The up and down movement of the catch, due to the spring 45 and the tripper 49, is limited by a pin 59 engaging a slot 60 provided in the catch.

It will thus be seen when all of the trips 55 of the disconnectors 48 are held by the springs 57 in a position to engage the trippers 49, that inasmuch as these disconnectors are mounted on a stationary portion of the frame, indicated at 61, as the tripper 49 and the catch 41 are carried successively toward these disconnectors 48 by the movement of the bar 36 to which they are connected, then the catch 41 will be successively disengaged from the several stops 16 with which it has been successively connected on the continued movement of the carriage.

It is often desirable, however, to regulate the. times at which the connector for connecting the computing mechanism to the carriage shall be disconnected. For this purpose', each of the disconnectors 48 is provided with a control 62 which is adapted to render its particular disconnector inoperative. for the purpose of disconnecting the catch 41 from the stops 16. In this instance, the control is shown as embodying a shifter 63 having a depressed portion 64 and a raised portion 65, the latter being adapted to engage a pin 66 provided on the toe end of the trip 55, so that when the shifter 63 is moved to the position illustrated in Fig. 11, the toe end of the trip 55 will be raised out of cooperative alinement with the notch 53 of the tripper 49. The shifter 63 is arranged in such a manner that it will be automatically held or detained in either of its adjusted positions, so as to permitthe trip 55 to be maintained in either of its positions without danger of accidental disarrangement. F or this purpose, there is shown a. lever 67 adapted to be manipulated by a handle 68, and pivotally mounted intermediate its ends in any suitable manner, as by means of a pin 69. The lever 67 is adapted to operate the shifter 63 through the medium of a pin 70 direction may be determined by the pin 7 4 engaging with a slot 75 in said shifter. It will be seen that when the lever 67 is in the position shown in Fig. 11, the spring 72 will extend along the line on one side of the pin 69, so as to hold the parts in the position shown in Fig. 11. When, however, the lever 67 is shifted, as by moving the handle 68 to the right in Fig. 11, there will at first be no movement of the shifter 63 as the handle 68 passes the line joining the pin 69 and the pin 74; As the lever 67 continues to move,

however, the right-hand end of the slot 71,

shown in Fig. 11, will engage the pin 70 and positively move the shifter 63 toward the left. This movement will continue until the right-hand end of the slot 75 of the shifter 63 engages the pin 74. In the meantime, the spring 72 is moved over to the right side of the pin 69 and exerts its ten sion to hold the parts in the position to which they have been moved, and which position is shown in Fig. 2. This, therefore, provides an automatic latch for securing the shifter and its actuating. means in either position of adjustment.

For a final disconnector for disengaging the catch 41 from the stop 16 at the limit of capacity of the computing mechanism, there is provided a pin 76 which will always operate to engage-the tripper 49 and thus depress the catch l1.

It is often desirable to provide manual -means for disconnecting the computing mechanism from the typewriting carriage, as for example, when it'is desired to do considerable typewriting without computing, which in this'case may be accomplished by a rotating the shaft 33 a sufiicient amount when the master wheel 21 is at the beginning of its movement, to force a cam surface 7 rovided on the catch ll against a roller 78, whereby the catch 41 will be depressed out of engagement withv one ofthe stops 16 with which it is in engagement at that time. If the catch does not happen to be in engagement with the stop, it will be depressed so that it cannot engage with any of the stops so long as the shaft 33 is rotatedto its extreme position, as indicated in Fig. 5. This extreme backward rotation may be accomplished by a control 79, which is shown in the'formof a lever 80 adapted to opcrate a pivotally mounted arm 81, which in turn engages, by means of a pin 82, a shoulder 83 provided. in a raised disk 84 having a recess 85- cut therefor. The disk 84 is secured to the gear 32, which in turn is secured to the shaft 33,so that any movement 'of the pin 82, when the disk 84 is in the position shown in Fig. 1, will rotate the shaft 33 and the disk 84 to the positionillustrated in Fig. 5. Here also a lost motion is provided between the lever 80 and the arm 81 by means of a pin 86 on the arm 81 engaging in an arcuate slot 87 provided in the'lever 80. This lost motion permits the parts to be latched or detained in either position of adjustment by means of a spring 88 which is secured at one endto the lever 80 and at its other end at such point beyond the pivot of the lever 80 that it will extend on opposite sides of the pivot in the two positions of adjustment of the lever 80. It is to be noted that this control for manually disconnecting the traveling member of the computing mechanism from the carriage can only be operated when the parts are in the position shown in Fig.

1, that is to say, before the commencement of a computation. This will be seen more clearly by reference to Fig. 6, where it will be seen that an attempt has been made to depress the lever 80 before the pin 82 has engaged shoulder 83, so the pin 82 has struck the circular surface of the disk '84, and is prevented from further movement because of the fact that the pivot of the arm 81 and the lever 80 is located eccentric with positioner or aliner is provided, which is shown to embody a detent 89 in the form of a spring-pressed pin 90, which-is beveled equally in both directions to engage a socket 91 provided in therack bar 31. This detent is positive enough to hold the master wheel and some parts connected thereto in proper initial position, and yet permits the movement of these elements when they are positively manipulated the letter-feeding movement of the carriage. In order to prevent rebound of these elements when they are returned to their starting position after each line, there is provided a shock-absorber 92 which is shown in the form of a piston bufi'er 93 yieldingly held in one position by a spring 94, the tension of which may be adusted to a nicety', by means of an adjustment nut 95 engaging the screw threaded end 96 of the-bufi'er 93. The particular position of the master wheel with respect'to the numeral or computing wheels 28 may be indicated by a pointer 97 carried by the rack bar 31 and located in register with the master wheel 21.

Considering the operation of the device, it will be noted that the computing wheels 28 (Fig. 1) are divided into groups ofthree computing wheels, with a letter-space .interval between groups. Such groupin is used in computing -mere numbers, whi e if dollars and cents were to be computed, other groupings might be used.

In the embodiment illustrated the disconnectors, or rather the trips 55, are so spaced as to give a range for the traveling master wheel between each two disconnectors of two groups of three computing wheels or six computing wheels in all. Longer or shorter distances between trips 55 might be used to give larger or smaller ranges. That is to say, in the present illustration, this gives a capacity of 999,999 for each computing zone or major column between disconnectors. The first major column may be made considerably larger depending on the distance of the first picking up stop 16 from the point of disconnection by the first trip 1f larger intermediate computing zones or columns than six digits vare desired with this spacing of the trips 55 after the first major column or zone, one or more of the trips 55 can be silenced. The stops 16 which are to pick up the catch 41, and thus the master wheel, are so set on the rack bar 19 that they will engage the catch 41 at the beginning of the computing zone so that if necessary a number of six-digit magnitude, such as 123, 123, could be computed between every two disconnectors. However, ordinarily numbers of this magnitude would not be computed, and although the stop 16 picks up the master wheel at the beginning of the zone, it will travel idly for one or more letter spaces according to the magnitude of the number being computed, and also to allow at least one letter space for tens carrying. The initial digit column computed in will depend on the particular tabulat ng or plunger stop 14 which comes up into the path of the carriage-carried stop 16 which is by this time in engagement with the hook or latch 41.

In Fig. 2 the carriage is shown as traveling after having engaged one of its stops 16 with the latch 41, so that the master wheel is traveling with the carriage. The particular digit column or letter space'in this computing zone at which the carriage stops and at which the master wheeL stops for the first digit to be typewritten and computed, will depend upon the particular tabulatin-g or plunger stop 14 raised to intercept the carriage stop 16. As each successive digit is typewritten and computed the carriage will move step by step toward the right in Fig. 2. The catch 41 will be drawn along with the carriage, and thus likewise the rack bar 36. This movement will rotate the gear 34 through the intermediary of the gear 35, and thus rotate the shaft 33 which rotates the gear 32 located at the front of the machine, and meshing with the rack 31. The rack 31 is thus advanced so that it carries the arbor 22 and the master wheel 21 through the series of disks 25 step-by-step wheel will rotate the disks 25 corresponding amounts, so that the numeral wheels 28 will be turned to the same extent, through the intermediary of the gears 27.

Considering Fig. 2 again, it will be seen that when the carriage has traveled to such a distance that the tripper 49 carried by the rack bar 36 comes in engagement with the toe 54 of the trip 55, said tripper will be rocked on its pivot point, so as to depress the catch 41 and withdraw it from engagement with the stops 16. A further movement of the carriage will bring this particular stop 16 in engagement with the roller 56 of the particular disconnector 48, and rock the trip 55 so that the toe 54 thereon will be removed from engagement with the notch 53, whereby the tripper 49 and the catch 41 are permitted to return to their normal postop comes in contact with the catch 41, it

will force the same down and engage in the seat provided therein, so that the master wheel of the computing mechanism will traverse the next series of computing disks. The point at which this next stop is set will determine the beginning of the next computing zone. During the first-connection of the catch to the first stop the machine may have been calculatlng a numeral in one column of figures or computing zone, and

between the disconnection of the catch from the first stop and its connection with the second stop the machine may have been used to insert explanatory notes or merely give a long space on the work-sheet. When the second stop carries the catch along with it, and thus feeds along the traveling element of the computing mechanism, the computing may again be carried on. The computation does not necessarily begin at the computing wheel in register with the master wheel at the instant of pick up by the stop 16, but may be started at any succeeding computing wheel in this zone depending generally on the selection by the operative who strikes a particular key 18 and-brings into play the desired one of the plunger stops 14 to deond stop will be determined by the location of the next active disconnector 48. This maybe the secondone counting from left to right in Fig. 2, or the third, fourth and so on.

i If it is not desired to disconnect the catch at the interval of movement of the carriage corresponding to the distance between the first and second disconnectors, it is merely necessary to silence or disable the second disconnector, and the third, fourth,'and so on, if also desired, as has been explained above. This is done by shifting the control for the disconnector so that the toe 54 on the trip thereof is. raised out of alinement with the shoulder on the tripper 49. The next operative disconnector will therefore trip the catch 41 from engagement with the second stop, so that the traveling element of the computing mechanism,'which in this case is the master wheel, will reniain passive once more, while the carriage is permitted to move on during the spacing thereof during major columns or computing zones, or for the purpose of interspersing typewritten matter between the columns of figures to be computed. This action continues, each successive stop 16 engaging with the catch41, so that the movement of the carriage is utilizedfto move the traveling elementof the computing mechanism the desired extent, which is determined by the distance between the last disconnector in action and the next active disconnector. Of course it is to be understood that any of these disconnectors, even the first, can be rendered inactive, and

in fact all of them can be rendered inactive if so desired.

When the carriage reaches the limit of its travel to the right in Fig. 2, the final disconnector 76, shown in the form of a pin, willengage the tripper 49 and shift the catch 41 out of engagement with the stop with which it happens to be connected. On the return movement of the carriage toward the left in Fig. 2, for a new line, the first stop 16 coming in contact with the catch 41 will engage ,the tooth 42 on the right hand side somewhat in the position illustrated in Fig. 10, and will carry the catch 41 and the bar 36 back with it toward the left until the to travel to its starting position. Any subsequent stops passing over the catch 41 will merely force the catch down against the tension of the spring 45, so that it wave'rs back and forth. t

It will be seen that this movement returns the traveling element of the computing mechanism, that is, the master wheel 21, to

its extreme left hand position, as viewed in Fig. 1, where it will be caught in the position just ready to enter the initial disk of the computing mechanism. The shock absorber.

92 is nicely tensioned so that there will be little or no bounce or jar of the master wheel as it returns with the carriage, although the i v ternately fed step-by-step through the computing disks and allowed to remain passive between the successive points of computation or computingzones determined by the position of the stops 16 and the active disconnectors 48. If it is desired-at any time to entirely disconnect the computing mechanism from movement with the carriage, so that the typewriting mechanism can be used without shifting the traveling element of the computing mechanism, it is merely 1 necessary to throw the lever 80 from the position indicated in Fig. 1 to the position indicated in Fig. 5,.which, however, can only be done when the master wheel is at its initial position to the extreme left of the cOmvputing casing, as indicated in Fig. 1. I This movement will shift the disk 84 by engagement of the pin 82 with the shoulder on said disk, so that the shaft 33 is rotated an abnormal amount toward the left, whereby the catch 41 is thrown against the throwout roller 78, whereby the catch will'be cammed down out of engagement with the stops 16, and in fact so far down that it cannot engage with any of said stops during the movement of the carriage.

Inasmuch as the lever 80, as illustrated in Fig. 5 is automatically held by the spring 88, the parts will be thus automatically maintained in disconnected position until positively rearranged by'a manipulation of the lever 80. The spring 88 also acts as will be seen in Fig. lrto hold the lever in operative position by the swingin of the spring 88 to the opposite side of t e pivot of the lever 80.
